Overview

● Applications● Components● Gathering Requirements● System Models

Applications

● Assembly and Quality Assurance in Manufacturing

● Food/Agriculture ● Traffic ● Security● Many, Many More

Typical Components

● Camera

● Optics(Lenses)

● Illumination

● Image Acquisition Hardware

● Machine Vision Software

Requirements Gathering-General

● Who are the Users or Support Personnel?

● What is the purpose of the system?

● What will it be looking at?

● Will the object be moving?

● How fast will it be moving?

Requirements Gathering-Hardware

● Camera– Analog– Digital

● Area Vs Line Scan

– Color / Grey Scale / Black and White ● Optics

– Focal Length– Viewing Angle

● Image Capture Card

Object Oriented Systems

● Benefits– Allows for levels of abstraction between hardware

and software– Extremely Flexible– Extensible/Scalable

● Drawbacks– A lot of Overhead

Client Server Systems

● Benefits– Allows storage of data away from the shop floor– Allows for remote access– Automated corrective measures– Easy reprogramming of Client nodes

● Drawbacks– Computers' sensitivity to dust and heat– Added expense of networking equipment and

software

Neural Networks

● Cognitrons/Neocognitrons
